Just few of the power plants this Prototype was running on over the years.


Now fitted with the 8S set up, L. after the last 6S unit on R. New 3D printed bell rings.


With the new thrust tube.


ESC reprogramming to suit new power system.


First day out.


Perfect flare.


In action.
Another change over after getting hands on this full metal 90mm power unit, running on 8S, sounds pretty nice, enjoy.
